I have a 2003 JD 4310, E-Power Reverser. It has the electric PTO switch. When you pull the switch, it instantly engages the PTO. I have had a real time trying to start my 513, 5' rear cutter with this setup. Even at idle, when the PTO engages, it is so sudden, that the swinging blades on the cutter will snap out, and about 1 in 3 times, take out the shear bolt on the PTO shaft. It has gotten a little better with time/use, but still happens too often. If anyone knows how to adjust the start up of the PTO to engage softer/easier, I would sure like to know.
I have been thinking of getting a slip clutch for this cutter cause it gets real old having to replace broken shear bolts, just from starting the PTO.
I haven't had any problems with it using the post-hole digger, or snow-blower, but they don't have the rotating mass that the cutter has either.
I don't understand why JD didn't build these to engage gradually, instead of instantly. It is a real P.I.T.A.
